First of all: This is a Z-series movie. This means, done with few money, with zombies and monsters and this kind of stuff. Surprisingly, the film results quite entertaining, although the actors don't play a good part, the story is so absurd that this is not necessary. In addition the screen play is very well done (the best of all the film), which makes the story amusing. Special effects are not bad, neither good. The film is good, but remember, you will see lots of free violence in a Spanish "cutre" (impossible to translate) way, with a very dark sense of humour and of course, lots of lots of blood and internal organs of human bodies. If you are a little exigent about the films you see, it is very possible that you hate this film, if you are more open-minded and you can watch something offensive without losing your nerves, you will like this film. In few time it will be considered a cult movie, in the same way as "toxic avenger", bad, very bad but funny, very funny.
